AI Summary
Combined cataract surgery and canaloplasty for open-angle glaucoma safely and effectively lowered eye pressure and medication needs more than canaloplasty alone over three years.
Abstract
Purpose
To report 3-year results evaluating the effect on safety and efficacy of canaloplasty to treat open-angle glaucoma when combined with cataract surgery.
Patients and methods: This was a retrospective subset analysis of a prospective, international, multicenter study evaluating 133 eyes of 133 adult, open-angle glaucoma patients who underwent canaloplasty with tensioning suture placement. Eighty-two phakic eyes that received canaloplasty alone were compared with 51 eyes that underwent cataract surgery before or during canaloplasty.
Results
Phakic eyes that received combined cataract-canaloplasty surgery (phacocanaloplasty) had a mean±SD baseline IOP of 23.5±5.2 mm Hg and mean glaucoma medication usage of 1.5±1.0 decreasing to a mean IOP of 13.6±3.6 mm Hg on 0.3±0.5 medications at 3 years postoperatively. Pseudophakic eyes undergoing canaloplasty had a mean baseline IOP of 23.9±5.2 mm Hg on a mean of 1.8±0.8 glaucoma medications decreasing to 15.6±3.5 mm Hg on 1.1±0.8 medications at 3 years. In phakic eyes, reductions in IOP were significantly greater and less postoperative IOP lowering medication was needed after undergoing phacocanaloplasty compared to eyes which had canaloplasty alone.
Conclusions
Clear corneal phacoemulsification performed before or in combination with canaloplasty is a safe and effective surgical procedure to reduce IOP in adult patients with open-angle glaucoma.

In a retrospective subset analysis, 82 phakic eyes that received canaloplasty alone were compared with 51 eyes that underwent cataract surgery before or during canaloplasty in adult, open-angle glaucoma patients.
